There's a lot of validity to what you say. You can actually see those striations under 200x magnification. However, a hair looks like a tree trunk next to them. Those tiny striations are like pins that stick up from the edge. I haven't been able to see it (200x is not enough), but I assume what happens when you shave is that the pins turn on an angle (sideways to the blade) instead of facing straight up. When they turn sideways, it makes the edge seem wider. Stropping would stand up those pins and make the edge narrower (sharper).
But I noticed something else that is also interesting. The edge has scratch marks that are on a much larger scale than the pins. They run crosswise along the entire edge and back on the entire width of the edge (about .5-1 mm). As you hone with finer grits the lines get narrower. If you use the x pattern, a pasted strop produce lines that cross the other lines. So, if you use the x pattern, stropping goes across the scratch marks. Leather (only) stropping polishes the lines and can make the finest lines fade.
The scratch lines are like treads on a tire and produce friction, because they come into contact with the skin behind the edge. For comfort, you would want to minimize them. With the x pattern, when you go to the pasted strops you break up the scratches because you go across them, but there are still some coarse portions. If you hone straight across the stone, everything would be parallel, and the pasted strops would break up the coarser scratch lines. Leather stropping should then give you a much smoother edge.
If you think of shaving as just a pushing operation (ignore the scything motion), angled scratch lines present more of an area to the skin than ones which are perpendicular to the edge, so you would expect angled scratch lines to have more friction (less comfort).
Manufactured blades, like Feathers all have scratch lines that are perpendicular to the edge.
Everything I've seen suggests that honing parallel to the stone should produce a better edge than the x pattern. Maybe the x pattern is only historical and a result of narrow stones.
BTW, the pins are so small that you barely see them at 200x. If you're using an 8 inch stone, the scratch lines are at about 15 degrees. As it is, the spacing between pins is much smaller than the thickness of a hair. A 15 degree angle could hardly make a difference in that spacing.
If someone has a microscope that can magnify more than 200x, we could learn a lot.

Thanked: 2209Hello Joe,
Good post!
I would suspect that due to the narrowness of the old hones an X pattern was necessary. A 3" wide stone I have not seen in any farm auction,estate sale,tool collector meeting.
You point about the effect of using a stropping motion I agree with. It would reduce the height of the ridge on the scratch pattern and thus present a thinner cross section and less abrasion to the face.
My take on this is that people will use either a toe leading or scything motion when they have shaved for awhile. If they do that then the perpendicular stroke on the hone may actually increase the irratation.
I guess you and I would have to get together to fully explain ourselves. But then, most of the guys here will try the two and decide for themselves.

There's a lot of work to be done before we really understand honing and shaving.

Thanked: 2209From here on use light pressure on this razor and MUCH! much fewer laps IF! you hone it again. Your strategy now it to creep up on perfection, a little at a time. Be patient and consistent in the number of laps used. That way you will learn the rate of change that occurs with that razor and a specific sequence.
teh main thing you are trying to avoid is overhoning. The perfect edge is just a breath away from overhoned.
Hope this helps,

There is a link to the video on the fourth post of this thread...
I have found one good reason to use the x pattern I'd like to mention. I have found that honing on a stone that is not completely trued only works if you use an x pattern. I believe this is because you drag the blade down over the resultant hump and it gets honed, slowly but it works. I wonder if the X pattern was designed to prevent the effects of a slightly concave center of a hone from "poor" maintenance from having an effect on honing. ????
Next, if industrial blades are striated parallel to the edge would it not make sense to use an exaggerated x pattern and see if that works? I'm willing to give it a shot if you guys agree with the thought....
Finally I wonder if the x pattern somehow shears the edge flat and is less likely to build and overhoned irregular edge.
I guess in aggregate I'm wondering if the x pattern is really based on the striation patterns and whether barbers and honermiesters of the day really worried about the striations at all. I have a sense that many of them didn't even look at the blade with a microscope.

Thanked: 4942Larry, Unless a DD Wonderedge's edge is rough or really in bad shape, starting at 15 strokes may be too much. I usually start with 5 strokes on the pyramid down on these razors and if not perfect, work with 1-3's from there. Lynn

As I understand this, you went straight down the stone, with the razor perpendicular to the length of the hone (not heel leaing). This worked when the x-pattern didn't? I'm looking for these kinds of comparisons.
Did you take any microscope pictures of this edge?
Since you're experienced and successful with this kind of honing there's no reason not to use it all the time.

But it seems like you want to hone. If so, get yourself a cheap razor and hone it to oblivion. It's not the way to treat a razor of value.
